In 1898, the German government lodged a protest against the use of the Mark IV [dum-dum-like] bullet, claiming the wounds produced by the Mark IV were excessive and inhumane, thus violating the laws of war...
...the American military delegate, Captain Crozier, whose country was about to make use of them in the Philippines [, defended dum-dums, saying:] "The civilized soldier when shot recognizes that he is wounded and knows that the sooner he is attended to the sooner he will recover. He lies down on his stretcher and is taken off the field to his ambulance, where he is dressed or bandaged. Your fanatical barbarian, similarly wounded, continues to rush on, spear or sword in hand; and before you have the time to represent to him that his conduct is in flagrant violation of the understanding relative to the proper course for the wounded man to follow - he may have cut off your head."
